Cassava is a staple for one in ten people on earth, grown mostly by small farmers tending a few acres. One of the challenges is insect-vectored virus Cassava Brown-Streak Virus that destroys the root.
Scientists from Africa and the Danforth Center in St. Louis MO, USA have collaborated to create a cassava line that is genetically engineered to suppress the virus.
The approach is similar to what was done to save the papaya in Hawaii, essentially using a portion of the virus sequence to shut down viral infection.
In this week’s podcast Dr. Douglas Miano, Professor at the University of Nairobi, describes the problem and the solution. as well as how the technology may serve farmers in Kenya and the entire African continent.
